在两个实验中，研究了在模拟的3-D场景中的物体的感知布局的整体深度的变化信息的效果。向受试者展示模拟纹理表面的显示器，这些显示器在深度上后退。成对的标记在场景内以相等的间隔定位。受试者的任务是判断间隔之间的深度。通过准直透镜或玻璃盘观察，改变整个场景的深度。判断的深度为相等的深度间隔减少，从现场的前面的间隔的距离增加。判断的深度是更大的准直比非准直观看。有趣的是，准直观察导致了感知深度间隔的均匀重新缩放。
The effect of varying information for overall depth in a simulated 3-D scene on the perceived layout of objects in the scene was investigated in two experiments. Subjects were presented with displays simulating textured surfaces receded in depth. Pairs of markers were positioned at equal intervals within the scenes. The subject's task was to judge the depth between the intervals. Overall scene depth was varied by viewing through either a collimating lens or a glass disk. Judged depth for equal depth intervals decreased with increasing distance of the interval from the front of the scene. Judged depth was greater for collimated than for non-collimated viewing. Interestingly, collimated viewing resulted in a uniform rescaling of the perceived depth intervals.
